NON-REFILLABLE BOTTLE.

To all whom, t may concern.'

Be it known that I, CONRAD M. CONRAD- SON, a citizen of the United States, residing in Madison, in the county of Dane and State of l/Visconsin, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to and has for an object to provide an improvement in that class of devices known as non-refillable bottles, the object of the present invention being to provide means which will seat a buoyant valve in the neck of the bottle not only when the bottle is in a vertical position, but when it is in every other position except an inverted vertical position and in which when in such inverted position the valve will seat of itself upon an attempt to force liquid within the bottle. The seating of the valve, however, will be overcome when liquid is flowing out from the bottle.

In the drawings accompanying and forining a part of this specification, Figure 1 is a central vertical section of a bottle equipped with my present improvements; and Fig. 2 is a similar view of the neck portion of a bottle, it being shown in a horizontal position and the parts shown in the position they assume when the buoyant valve is forced to its seat by a suitable non-buoyant weight provided therefor.

The bottle is shown as having a breast portion 8 and a neck portion 9. The juncture between the neck and breast is shown contracted, as at 10, and the inner and upwardly-projecting face 11 of such portion is made conical to provide a valve-seat. This valve-seat may be ground to a truly-conical surface without adding much expense to the cost of manufacture. The valve for seating upon this seat must be buoyant and in the present instance is shown as a hollow sphere 12, which may preferably be made of glass, and this may be ground upon the entire outer surface in a modified ball-grinding machine. By this grinding of the ball and the seat an accurate fit is had at all times. The valve when spherical, as shown, will roll into its seat and needs no guiding of any kind other than its seat.

The baffle-plate for insertion in the mouth of the bottle for closing the same is illustrated in Fig. 3 and comprises a series of ribs 13, 14, 15, and 16, which are formed in a conical plane for engaging a conical face 17 at the mouth of the bottle. These faces may in some instances be ground for greater accuracy. This conical face gives a sure fit, and in case of any variation in sizes of the bottles or of the baille-plates a sure and accurate fit will be had at all times. The channel 18 between the flanges 13 and 14 constitutes a seat for a locking device, the form of which illustrated comprises a wire 50, having a series of crimps or bent-up points. The wire may easily be inserted in the channel 1S and the baffle-plate inserted in the mouth of the bottle, the points riding over the portion 20 of the conical face 17 and then springing out into a chamber 21 in such face 17. If desired, the wire may be so formed that it will be under compression between the faces 22 and 23 on the baffle-plate and in the neck when the baffle-plate has been seated. The baffle-plate has within it a chamber 25 for receiving the ultimate closure of the bottle and which constitutes the pouring-port, which in many instances will be a simple cork. The chamber 26 between the flanges 14 and 15 may receive a bushing 27, of some suitable material, such as cork, for making the bafl'leplate liquid-tight in its closure of the neck of the bottle and also for preventing its passage to the locking device in the chamber 18. The liquid in passing from the neck of the bottle to the chamber 25 will traverse interruptions 2S in the ange 1,6 and then the channel 29 between the flanges 15 and 16 and then will flow through an opening 30 into the chamber 25.

There is provided at the mouth of the bottle and above the valve-seat when the bottle is standing in a normal vertical position a convex projection which may be of equal radius with the ball-valve 12, and such projection (designated herein by 31) is carried by the baffle-plate. The buoyant sphere 12 will act as a valve, closing upon the valveseat 11 upon any attempt to pass liquid into the bottle when the bottle is in an inverted position and will move away from its seat upon the outward flow of fluid from the body of the bottle. To close the valve against its seat when the bottle is in other positions, there is provided a weight 35, which in the resent instance is shown as cylindrical and iaving depressions 36 at each end, which depressions in the present instance are shown as conical, in one of which depressions the ball-valve is received. When the bottle is in a vertical position, as illustrated in Fig. l, the weight will rest upon the valve 12 and hold it to its seat. Upon tipping the bottle at even a slight angle the weight will not only rest upon the ball, but will engage the face 3l and so tend to force the valve to its seat. Upon turning the bottle into a greater angle from the vertical or toward the horizontal the parts will assume the position shown in Fig. 2-that is, assuming there is no discharge of the contents of the bottle at the time-and the weight will then hang upon the ball l2 and upon the face 3l, pressing the ball to its seat, and will continue so to press,

it even when the bottle is turned into an angle considerably below the horizontal. Upon passing such angle, however, the weight will still press the valve to its seat ;y but after that the pressure of the valve by the Weight is unnecessary, since any attempt to force liquid into the bottle will lioat the valve against its seat, and thus prevent the fraudulent reiilling of the bottle. The weight will fall away from the valve in pouring out the contents of the bottle at a time when the volume of the outflowing liquid is not great, and thus the entire contents may readily be discharged, which would not be the case if the pressure of the weight were as great at the end as at the completion of the pouring operation.

As this bottle is designed in a horizontal position, the lateral component of the force due to the weight is about iive times the horizontal component of the weight of the ball. This insures very prom t seating of the valve and at an angle consi erably below the horizontal.

The bottle, of course, will be filled before the various portions of the closure are inserted. Then the ball will be laced in position and u on it the weight. T e baffle-plate will then e inserted, and then the cork or closure will be seated in the chamber 25.

When it is desired to remove the contents of the bottle, it is merely necessary to draw the cork and pour fromthe bottle, as in ordinary structures; but it will be impossible to introduce liquid into the bottle, since when the bottle is in a vertical upright position the y bottle is in a relatively horizontal position.
